Knife Blade Steel Chart & Guide
Comparing pocket knife and kitchen cutlery steels: MagnaCut, S30V, D2, and VG-10. Understand edge retention, toughness, and ease of sharpening.
Select A Blade Steel Composition:
Super Steel
CPM MagnaCut
Hardness: 61 – 64 HRC
Edge Retention:9/10
Toughness (Anti-Chip):9/10
Corrosion Resistance:10/10
Ease of Sharpening:7/10
The holy grail of modern pocket knife metallurgy designed by Dr. Larrin Thomas. Incredible balance of near-indestructible toughness, stainless corrosion resistance, and prolonged edge retention.
Key Metallurgy Factors to Consider
Edge Retention
How long the blade holds a working cutting edge before needing sharpening.
Toughness
Resistance to chipping or snapping under hard lateral stress or batoning.
Corrosion Resistance
Ability to resist rust, acid corrosion from lemons/food, and saltwater pitting.
Rockwell Hardness (HRC)
Standard indentation hardness scale. 58-60 is balanced; 62+ is ultra-hard but more brittle.
